UpdateViewportCache looks like it might be low hanging fruit as well.

The spec has this to say.

"
All resources associated with surface which were allocated by EGL are marked for deletion as soon as possible. If surface is current to any thread (see section 3.7.3), resources are not actually released while the surface remains current. Future references to surface remain valid only so long as it is current; it will be destroyed, and all future references to it will become invalid, as soon as any otherwise valid eglMakeCurrent call is made from the thread it is bound to."

The name mapping happens when an identifier is longer than 32 characters.  The name mapping is behind a flag, so it won't happen by default.  Also, functions to query the mapped names are added.

The purpose of this CL is for the drivers that can't handle long names.  For example, linux NVIDIA driver can't handle 256 character name, whereas WebGL spec requires that.

This CL also fixes the issue that some of the TIntermSymbols' ids are 0s.

If inside a for-loop, sampler array index is the loop index, Mac cg compiler will crash.  This CL unroll the loop in such situation.  The behavior is:
1) If the for-loop index is a float, we reject the shader.
2) If it is an integer, we unroll the for-loop.

Things that should be done in the future are:
1) Add line number macros.
2) Add a limit to unroll iteration count.
